摘要：

Two species of the Rosaceae genus Geum. comprising high amounts of tannins and phenolic acids, were investigated in terms of their antioxidant activity. Antioxidant potential of different extracts from aerial and underground parts of Geum rivale and G. urbanum was studied using various in vitro methods (FC, DPPH, FRAP and linoleic acid peroxidation test). The hydromethanolic extract from the roots of G. rivale with high total phenolic content of 17.48% was proven to be about twice as effective as the other extracts tested. Ethyl acetate and n-butanol were demonstrated to be the best solvents for optimal concentration of antioxidant constituents.
